THOMAS WRIGLEY, OF TODMORDEN, ENGLAND.

SPINNING-SPINDLE.

SPECIFICATION forming part of Letters Patent No. 492,080, dated February21, 1893.

Application iiled April 22, 1892. Serial No. 430,187. (No model.)

To all whom. it may concern:

Be it known that I, THOMAS WRIGLEY, of Waterside House, Todrnorden, inthe county of York, England, have invented a new and usefulSpinning-Spindle, ot' which the following is a specication, referencebeing had to the accompanying drawing, making a part hereof, which is alengthwise section illustrating my spindle, and in which A is thesupporting tube, B the spindle, O its sleeve whirl and D apost, confinedwithin the supporting tube, and entering a bore in the spindle.

I have shown the upper end of the supporting tube with a bushing o,which I prefer to force tightly into the upper part of vthe supportingtube; but which may, if preferred be adapted for a slightlateral motion.Although it is indifferent whether this bushing a, be tight or loose inthe supporting tube, yet the bushing is desirable; for it acts as aguide when the spindle is put into the supporting tube.

I have shown the bushing a as driven tightly into the upper part of thesupporting tube, but with two grooves lengthwise so that e any oil whichmay be thrown off of that part of the spindle just above the upper endof the bushing, may percolate back into the supporting tube. The lateralor bolster bearing for the spindle is practically the side of the postand the lower end of the tubular part of the spindle and the stepbearing is the upper end of the post and the closed end of the tubularpart; in practice I have found it preferable on the whole to have theupper end of the post D practically in the plane of the band pull, asshown in the drawing, and to have the hollow part of the spindle B, eX-tend well down,the proportions shown being those preferred.

tilt when in rapid revolution, as required by the unbalanced load of thebobbin and the yarn upon it, the lower hollow part of the spindle willnot remain concentric with the post D; although the lm of oil alwaysbetween the interior of the tubular part of the As the spindle will tipor spindle and the exterior of post D serves as a cushion, and preventsgrinding and heating which might otherwise ensue from contact o'f thespindle with the side of post D. In practice I prefer tomake vent holesb in the hollow part of the spindle B, to allow circulation of oil. Thepost D may be driven firmlyinto la cavity made for it in the lower partof the supporting tube, or may have slight play in that cavity, so thatit does not revolve with the spindle.

I have shown the supporting tube with a middle sleeve a projecting wellup into the sleeve whirl O, as usual; but in addition I provide thesupporting tube A with a shorter sleeve o2, which extends up into a deepgroove O formed in the lower part of the whirl O. This feature isdesirablein all forms of sleeve whirl spindles, for if the space betweenthe Sleeves a a2 be wiped out from time to time no oil can be thrown outby the whirl.

What I lclaim as my invention is- 1. In combination a spindle tubular atits lower end; a sleeve whirl; a supporting tube whose upper portionextends up into the sleeve ol' the whirl; and a post Whose upper endforms in connection with the inner end of the bore the step or endbearing of the spindle and whose lower portion forms in connection withthe mouth of the bore the bolster or side bearing of the spindle; allsubstantially as set forth.

2. A spindle,a supporting tube with the long middle sleeve a', formingan oil receptacle, and also with a short outer sleeve a2, forming a dripcup for oil; in combination witha sleeve Whirl surrounding but notrevolving upon the middle sleeve a and grooved at its lower end toreceive the outer'sleeve a2, all substantially as set forth.

In testimony whereof I have hereto affixed my signature in presence oftwo witnesses.

THOMAS WRIGLEY.
